    I actually do not plan on replacing the radix code in this round.
    I want to see how it performs before I vote it out. I don't currently

            ccdconfig -c ccd0 128 0 /dev/da0b /dev/da1b /dev/da2b
            swapon /dev/ccd0

Never attribute to malice what can adequately be explained by incompetence.
